Spred-Lok inserts are high-quality one-piece, brass, knurled inserts with a unique, slotted, expandable outside diameter. They can be installed in either thermoset or thermoplastic materials.
No special tooling is required; Spred-Lok inserts are simply pressed in. The mating screw expands the insert, locking it in place, and the insert provides a locking action preventing the screw from loosening under vibration.
The inserts can be used in through or blind holes and are available with or without a flange.
